How would it be possible to allocate more address space than is addressable? calloc returns NULL when can't satisfy the request. The idea of taking two arguments is not to allow the user to specify a larger requested size, but to protect against overflows as it can happen with e.g. malloc() where the user has to compute the size of arrays by multiplying NUM_ELEMS * SIZE_PER_ELEM. And the user will normally do so less carefully than a library function. |
